Microsoft Security Response Center

**What privileges could be gained by an attacker who successfully exploited the vulnerability?** An attacker who successfully exploited this vulnerability could create or delete files in the security context of the “NT AUTHORITY\\ LOCAL SERVICE” account.

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** An attacker who successfully exploited this vulnerability could trick Windows Code Integrity Guard (CIG) into trusting the file the attacker altered to contain arbitrary content bypassing CIG integrity checks.

**How could an attacker exploit this vulnerability?** To exploit this vulnerability, an unauthenticated attacker would need to send malformed packets to a RPC host. This could result in remote code execution on the server side with the same permissions as the RPC service.

**here is the question** here is the answer

**How could an attacker exploit this vulnerability?** An attacker could exploit a use after free vulnerability within the OS SAPI component to execute arbitrary code in the context of the compromised user to disclose sensitive information, compromise system integrity or impact the availability of the victim's system.

**According to the CVSS metric, user interaction is required (UI:R) and privileges required are low (PR:L). What does that mean for this vulnerability?** An authenticated attacker must launch a specially crafted malicious application and wait for the victim to perform a command in a console window for the vulnerability to be exploited.

**How could an attacker exploit this vulnerability?** An attacker could exploit this vulnerability by tricking a user into sending a request to a malicious server. This could result in the server returning malicious data that might cause arbitrary code execution on the user's system.

**What does the security update provide to mitigate the risks associated with this vulnerability?** The security update will prevent untrusted Microsoft Saved Console (MSC) files from being opened to protect customers against the risks associated with this vulnerability.

**According to the CVSS metric, the attack vector is adjacent (AV:A). What does that mean for this vulnerability?** Exploiting this vulnerability requires an attacker to be within proximity of the target system to send and receive radio transmissions.
